The VitalStim® Therapy System should not be used directly over an active neoplasm or infection. It should be used with caution in patients with seizure disorders and patients with implanted electronics (e.g., pacemakers, implantable defibrillators, deep brain stimulators). Some patients may not respond well to VitalStim. This may include patients with significant lower motor neuron damage and patients with severely impaired cognition. A certified VitalStim clinician can give you more information about candidacy for this treatment.
